Nick Coghlan added the comment: Yeah, it was only when we went to add test.pkg_helper (so that test_runpy and test_pkgutil could share it) that we put the brakes on and decided to stop making a bad situation worse and do something different. There are probably some other helpers we could spin out over time (like those for creating test servers).

[issue17585] IDLE - regression with exit() and quit()
New submission from Roger Serwy: This issue is a split from #5492, where Terry noticed a serious regression that quit() and exit() no longer work in IDLE. Before #9290, the PyShell object itself was stdin and it didn't have a fileno method. The code in site.py would skip over the call to fileno, leaving fd == -1, which then called close() on stdin, effectively the close() method of PyShell. The application of #9290 introduced PseudoFile as a subclass of io.TextIOBase which has a fileno method. The site.py code find it, calls it, but an error gets raised so that the close() method doesn't get called. Even if you subclass fileno(), you still need to subclass close() so that it calls the original close function in PyShell. The attached patch, fileno_close.patch, fixes that issue. I would argue that this patch should be applied to all the release candidates as it corrects a serious regression. I would like to hear your thoughts before applying the patch. -- assignee: roger.serwy components: IDLE files: fileno_close.patch keywords: patch messages: 185619 nosy: roger.serwy, terry.reedy priority: critical severity: normal stage: patch review status: open title: IDLE - regression with exit() and quit() type: behavior versions: Python 2.7, Python 3.2, Python 3.3, Python 3.4 Added file: http://bugs.python.org/file29618/fileno_close.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17585 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17585] IDLE - regression with exit() and quit()
Terry J. Reedy added the comment: I thought of this exact patch, but then decided against it. 1. The bug is in site.py -- see thread [Python-Dev] Idle, site.py, and the release candidates for a better explanation and solution. 2. The Idle behavior, inherited from io.IOBase is correct. 3. The consequence on *other* Python code of a fake fileno is unknown. The solution I gave for site.py is to begin .__call__ with if sys.stdin.__name__ == 'PseudoInputFile': sys.stdin.close() This should be safe to do without another release candidate. The name as seen by the user process should be checked but I cannot do so at the moment (on substitute substitute computer). This would only be done in the release by the file managers. The exact decision is up to them. So I would replace IDLE with site.py in the title. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17585 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

But I disagree that the problem of IDLE not exiting is due to site.py. Even if you fix site.py (which I did), calling sys.stdin.close() won't close IDLE since PseudoInputFile's close method doesn't call PyShell's close method. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17585 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17206] Py_XDECREF() expands its argument multiple times
Mark Dickinson added the comment: Amaury, why do you mention -R flag He's talking about the -R argument to regrtest: -R runs each test several times and examines sys.gettotalrefcount() to see if the test appears to be leaking references. The argument should be of the form stab:run:fname where 'stab' is the number of times the test is run to let gettotalrefcount settle down, 'run' is the number of times further it is run and 'fname' is the name of the file the reports are written to. These parameters all have defaults (5, 4 and reflog.txt respectively), and the minimal invocation is '-R :'. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17206 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17206] Py_XDECREF() expands its argument multiple times
Mark Dickinson added the comment:
Thanks for the updated patch. Some comments:
- In the tests, your functions should have return type PyObject* rather than
void; you can use Py_RETURN_NONE as a convenient way to return something of
the correct type. E.g.:
static PyObject *
test_decref_doesnt_leak(PyObject* self)
{
Py_DECREF(PyLong_FromLong(0));
Py_RETURN_NONE;
}
- Unfortunately, the test above *will* leak: even though your patch fixes
Py_XDECREF, Py_DECREF will still evaluate the argument multiple times. So we
get, for example:
iwasawa:cpython mdickinson$ ./python.exe -m test -R:: test_capi
[1/1] test_capi
beginning 9 repetitions
123456789
.
test_capi leaked [1, 1, 1, 1] references, sum=4
1 test failed:
test_capi
- It would be great to have tests for Py_INCREF and Py_XINCREF, too.
- The patch introduces two extra blank lines before Py_CLEAR.
- Not specifically about the patch, but: there's a comment in object.h that
reads:
*** WARNING*** The Py_DECREF macro must have a side-effect-free argument
since it may evaluate its argument multiple times. (The alternative
would be to mace it a proper function or assign it to a global temporary
variable first, both of which are slower; and in a multi-threaded
environment the global variable trick is not safe.)
I don't understand why the author of that comment ruled out the possibility of
a local temporary variable. Anyone have any ideas? A constraint of some
flavours of pre-ANSI C, perhaps?

[issue17587] Have all core library modules imported by default
New submission from Daniel Ellis: The other day I was trying to make a script to import a CSV file but for the life of me couldn't remember what the name of the csv library was (turns out it was csv). So I started thinking hey, what if all the standard library were just *there* by default? We all know doing imports is really boring, so why don't we deal with the elephant in the room? This is what I love about PHP: once something's imported (or required? included? required_once?) you don't have to think about it anymore. It's very set it and forget it. And then you simply remember it later when necessary. For this, I use pen and paper. Holy crap, I just had an even better idea. What if all third-party modules were imported as well? This may be a bit more challenging, but I truly believe you guys can do it. There are system settings I've heard about (Krons) that let you basically do anything over and over again. We could have Python automatically download all pips or whatever and import them without thinking. Boom! The Zen of Python. And can we put an and a $ somewhere in Python? I think these feel very cool to use, and are easily one of the best things I miss from more advanced languages like C and PHP. Let's be honest, doesn't this: $item-method(); Look a lot more professional than: item.method() It certainly justifies my salary a bit better. I don't have a patch for this because, let's be honest, I wouldn't know where to begin. But I can't imagine it being that hard. Is there a line or two we could change somewhere? Maybe just throw an import * into a header file somewhere? Finally, I propose replacing meaningful whitespace with meaningful random unicode characters. This would look like the matrix and once you got it it would feel really cool. With all of these changes I think we have the potential to turn this toy language into a powerhouse that could even be used for stuff like forum software. Let me know what you guys think of this.

[issue17206] Py_XDECREF() expands its argument multiple times
Larry Hastings added the comment: For the record: I care. Generally speaking CPython is a lovingly crafted source tree, and the choices its architects made are nearly always sensible and well-reasoned. When I see things like this, things that seem kind of dumb on first glance, I worry that we're missing something. It could be that it did have a sensible reason fifteen years ago, like some bone-headed compiler generated awful code--and the macros *are* used everywhere, so maybe performance genuinely suffered. Or maybe the macros were originally intended to be usable as rvalues; it looks like Py_INCREF still permits that, and changing it to be a statement could be considered a breaking API change. But we can't let ourselves become hidebound and superstitious. I see no reason why a local temporary variable shouldn't be fine here, and perhaps in all the macros Mark cites. So don't get me wrong, I'm +1. (The documentation on Py_INCREF makes no mention of whether it's legal as an rvalue, and all the examples use it as a statement. Perhaps we should document it explicitly so for 3.4.) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17206 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17584] collections.Iterator __subclasshook__ does not check if next() is callable
Raymond Hettinger added the comment: It's the nature of duck typing in a dynamic language. You can tell whether something is present but can't tell whether it words correctly until you call it. For example, in Python 3, all objects have __lt__ defined, but all it does is return NotImplemented. So, you can't really tell whether something is orderable until you make the less-than call. In your case, the rule is that if next is present, we assume that it is iterable, but it won't be until it is called that we can tell whether it is implemented correctly (i.e. is callable with zero arguments, returns a value, and raises StopIteration when done). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17584 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17589] Make documentation about macros in C API explicit about rvalue vs statement
New submission from Larry Hastings:
CPython API functions implemented as macros can expand into either
rvalues or statements. Most expand into statements (often using the
do {} while (0) syntactic sugar trick), but occasionally they're legal
as rvalues.
As of this writing Py_INCREF works as an rvalue. But discussion on
another tracker issue (#17206) proposes changing the implementation
in such a way that it will only be usable as a statement. Although
it's mildly unlikely, it's certainly possible that this will break
somebody's code.
I propose that the documentation make an explicit ruling on whether
macros are usable as rvalues or as statements. Perhaps a blanket
statement would suffice, all macros are only supported for use as
statements except where explicitly noted, then annotate specific
macros that are supported for use as rvalues. Though that raises the
question of acknowledging in the documentation that some things are
macros--I think the documentation glosses over that fact right now.
Note: I added you three (Georg, Mark, Martin) as I thought you might
have an opinion on this one way or the other. If you're not interested,
my apologies.

Now python evolve and minimum is xp. b) previous patch nos not define libm in configure script .

[issue17589] Make documentation about macros in C API explicit about rvalue vs statement
Antoine Pitrou added the comment: Py_INCREF usable as an rvalue sounds more like an accident than a deliberate feature, and it would be IMO counter-productive to codify this behaviour in the docs. As for the lvalue usage of Py_REFCNT and Py_SIZE, I think it would be better if it were limited to CPython core.

Generally speaking CPython is a lovingly crafted source tree, and the choices its architects made are nearly always sensible and well-reasoned. When I see things like this, things that seem kind of dumb on first glance, I worry that we're missing something. Did someone test the patch on a use case where the performance of this macro matters a lot ? E.g. deallocating large lists or dictionaries. Todays CPUs have plenty of registers available, so it's possible that the patch actually speeds up things, since the decref'ed variable may well be an indirect reference. At the time Py_DECREF was written, registers were precious golden flasks, only to be filled with the most valuable of things ;-) Just want to be sure we're not missing something... -- nosy: +lemburg ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17206 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17583] IDLE HOWTO
Ezio Melotti added the comment: I left a few comments on rietveld. I wonder if it's better to make two separate versions, one for py2 and one for py3, and avoid repeating things (like the name of the packages) twice. You should also be able to include the images in the patch by using hg add locally. This should include them when you do hg diff idle.patch (if it doesn't work you might have to set git = on (see http://docs.python.org/devguide/committing.html#minimal-configuration)). -- nosy: +ezio.melotti stage: - patch review ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17583 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue5492] Error on leaving IDLE with quit() or exit() under Linux
Roger Serwy added the comment: I found the root cause of the original error. Entering exit() at the shell raises SystemExit which gets written to the shell's text widget. The call to actually write the text passes through .write() in Lib/idlelib/OutputWindow.py, which calls text.update(). The call to .update() enters the Tk event loop and flushes pending events, including expired .after callbacks. Forcing the .after callback in .close() to 1 ms will always trigger the error. Commenting out the text.update() in OutputWindow.py avoids the error. The patch causes .kill_subprocess() to execute immediately which prevents the subprocess from writing to sys.stderr. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5492 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Amit Saha added the comment:
Hi Ezio, thanks for your review comments.
I will make the changes to the document, and also add the images in a later
patch.
I do agree that repeating package names for Python 2 and Python 3 is perhaps
not an ideal way. I am also trying to think of other ways to justify having two
separate documents: may be the code samples? print 'Hello world' versus
print('Hello World') ?
Thanks.

[issue17593] mailbox.py tries to link even on filesystem wihch does not support symbolic links
R. David Murray added the comment: The problem is that mailbox decides if links are possible based on the OS rather than on the file system. This is a general problem that Python has...when the Python file system APIs, and this code, were written, OSes could only read their own file systems, and there was only one file system type per OS. Fixing this, then, pretty much requires solving the general problem of introspecting file system capabilities. I think there are open issues relating to that. -- components: +email nosy: +barry, r.david.murray type: - behavior versions: +Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17593 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Todd Rovito added the comment: Roger, I reviewed and tested the patch, it does seem to fix the bug. Now when the on startup configure option is selected IDLE will behave as expected.
